FLOOR SCRAPER OR CLEANER.

Application led December 1, 1913.

lspecification.

My invention relates to newvand useful improvements 1n Scrapers and more partic- 'Aularly to Scrapers for cleaning the runways` of poultry houses, barns and the like, the object of my invention being the provision of a scraper which will thoroughly remove all waste matter from the runways and which is further adapted to spread sand, saw-dust or the like over the surface scraped. A further object of my invention is to provide the scraper with a floor engaging blade or knife which is swingingly mounted and to rovide means for varying `the force with w ich the blade or knife will engage the floorl being scraped.

A further object of my invention is to provide a winding drum and endless cable nected to the scraper', whereby rotation of thedrum in one direction will advance the scraper and rotation of the drinn in Athe opposite` direction'return the scraper to riormal position. l

In this connection', a still further object of my invention fis to so attach the actuating cable to the scraper that upon return movement of the scraper, the cable will act to antomatically'raise vthe blade or lcnileol the scraper out of engagement withI the loor.

My improved scraper is intended to occupy the entire width of the runway or' siii'- face being cleaned and i'or this reason l provide the body of the scraper with ,laterally directed rollers for engagen'ient against the Vwalls of the runway.

With these and other objects in view, my invention will be more fiilly described, illusthen Specifically pointed out iii the claims which are attached to and forni a part of this application. i

Corresponding and like parts are referred to in the following description and indicated in all the views of vthe drawing by the same reference characters. i

The body of my scraper consists of a substantially rectangular frame 10 including spaced side men'ibers 11 and l2 and a. transversely extending forward vbrace 13. The side members are identical in construction and a description of one will therefore silli- {ice for both. llach ol these side members is preferably kfoi-ined from a single piece of metal having its forward end bent upwardly as shown at 14 and provided intermediate its length and at its rear end with bearings 15 to receive ythe frontand rearaxles 16 and 17, these axles being secured against rotation in Vtheir bearings by set bolts 18, whereby the axles,ptogetlier with the brace 13, serve to hold the side members of the frame in proper spaced relation to each other. Supporting wheels 1!) are rotatably mount. ed upon these axles and are held `against lon-y gitudinal movement thereon by means of L- shaped arms 2() `preferably formed integrally with the side members 11 and engaging by their l'iec ends against the inner edges ol' the wheels. These arms are so positioned with respect to theI wheels as to serve as scrapcrs to remove any waste matter from the wheels. The side members of the trame immediately at the rear oii'eaeh axlebearing are provided with outwardly their lcngtl'i with downwardly directed aiiiis 2G, which may oi may not be integral with the rods, the lower ends ol which are pref,-y ciably inclined forwardly as shown at 27v to receive and support tlieblade or knife Q8 ot' the scraper, the blade being secured to these extensions by rivets or other suitable fastening devices Q9. The rods 25 at the rear of the arms zareconnected and maintained in suitable spacedy relation by a brace bar 30 to which the rods are secured by clevis bolts 31. Slidably mounted upon the free ends of the rods 25 are weights 32v `blade or knife engages the floor being i axle.

' scraped. The rods 25 are provided immediately at the rear of the brace rod 30 with downwardly depending ears 34 to which are pivotally mounted prongs 35, the free ends of which drag the floor during forward movement of the scraper. At this point, it should be noted that if the scraper is drawn rearwardly, these prongs will engage in the floor and serve to momentarily raise the rods 26 and consequently the scraper blade or knife. I

The outermost of the rods 25 upon either side are mounted eXteri'orly of the side members 1l of the frame but interiorly of the planes, of the rollers 23 and carry vertically disposed shields 36, each preferably consist ing of a single plate of sheet metal. These shields serve to prevent any escape of waste matter past the ends of the blade or knife during operation of the scraper and also serve as runners to prevent undue tilting of the scraper as a whole should the bladeube-r come caught upon any object project-ing from the floor, such as a nail head or knot.

Asubstantially rectangular shaped trough 37 is supported by the side members of the frame between the front and rear axles, this trough being provided with converging bottom walls 38 ',spacedapart at their lower edges to provide a narrow feed slot 39. The ends of this ltrough bear against the inner faces of the side members ofthe frame and are provided with outwardly and'downwardly directed extensions or lips 40 which engage over the side members of the frame and support the trough. In use, sand, saw-dust or other material is placed in the trough and feeds through the slot through vibration of the trough,due to movement of the scraper.

Mounted for turning' movement upon the central portion of the forward axle 16, is a sleeve 41, the turning of which is limited by a set screw 42 extending through a slot 43 formed in the sleeve and threaded into the This sleeve carries an integrally formed, radially extending cam 44 having a longitudinally groovcd, arcuate cam face 45. This cam is so proportioned that when swung to forward position, its cam face is spaced immediately below the brace 30 connecting the blade carrying rods 25 andwhen swung to rearward position, its-cam faccengages the bar 30 to raise thesame` and-con sequently to raise the scraper blade or knife. It will of course be understood .that this scraper may be drawnV backandffortlralong the runwayein any suitable manner but l: prefer topper-ate' it in the manner shown in Figs, l and 3 of the drawing for the reason that such an arrangement permits the automatic raising of the scraper knife or blade duringl return movement of the scraper. The construction shown for operating the scraper includes a housing 46 mounted' at one end of the runway and provided with bearings for a shaft 47 carrying a winding drum 48 and spur gear 49. This spur gear meshes with a pinion 50 carried by a stub shaft 5l also journaled in the housing and a handl crank 52 carried by this stub 'shaft serves as a means for manually operating thev winding drum 48.

A pulley 53 is mounted in proper position at the opposite end of the runway and a cable54 is wound for a number of turns about the winding drum and passed abouty the Pulley 53, being secured at its ends t0 opposite ends of the cam 44. lIntermediate portions of this cable .may be passed under.

suitable guide pulleys 55 carried by bracket 56, if desired.

Bars 57 are secured in the housing. immediately in front and at the rear of the winding drum 48 and are' provided with spaced teeth 58, the ends of which lightly engage against the peripheral face of the`,

winding'drum and serve to maintain the various convolutions of the actuating cable in proper spaced relation. These teeth`are so formed that the cable is wound helically about the winding drum and they therefore, in connection with the drum,- insure sufiicient frictional engagement of vthe* cable toI cause any turning of the winding drum to move the scraper. f.

In operation, assuming that the scraper'is at that end of the runway adjaicent [the winding drum, the winding drum is so ro tated as to draw the scraper toward the pulley 53. This rotation of the winding drum acts through the cable 54 to not only move the scraper, but to swing the cam 44 to raise the bar 30 and consequently `theV scraper blade or knife.

The engagement ofthe.

rons 35 in the floor of the runwa fas4 soon as the scraper starts to move,'.assists this operation. During this; movement, of

discharged from 'the-trough uponthe floor to coverl thejwaste' matter "ther, lVhen the scraperhas reached the .fa-igt er end of the runway, tljledirectiorA of rotation of the winding` drum isrevelysed. This 1re# `verses the direction of; ,movement .of the Cable 541 and causes everse swinging of the cam44'out of -engag" nent withthe bar thereby permitting" the-.scraper blade `or surface. It will be clear that by proper adjustment of the weights 32, the blade may be forced into any desired engagement with the Hoorand that by 'proper` adjustment of the width of the slot in the trough, any desired quantity of sand or saw-dust may be spread upon the Hoor.

I do not wish in any wayr to limit myself to the specific details of construction, illustrated in the drawing and described in the specification, as various minor changes, within the scope of the appended claims, may be made at any time, without in the slightest degree departing from the spirit of my invention.

In'order to prevent any escaping of waste over the upper. edge of the blade or scraper 28, I provide a shield or apron 59, prefer'- ably formed of sheet metal and loosely secured to the blade supporting arms 26 by clevisbolts 60, enough freedom being allowed this apron to permit tilting of the lblade in case the floor is uneven.
